IMPROVEMENT I N GRAIN=SEPARATQRS.

Specification forming part of Letters Patent No. 33,643, dated November12, 1872.

To all whom it may concern:

Be it known that I, EDWIN R. J. UEBER- ROTH, of Doylestown, in thecounty of Bucks and in the State of Pennsylvania, have invented certainnew and useful Improvements in Grain-Seperator; and do hereby declarethat .the following is a full, clear, and exact de Figure 1 is a sideelevation, and Fig. 2 a

vertical sect-ion of my machine.

The frame-work of my grain-separator consists simply of four uprightposts or standards, A A, suitably braced andconnected by bars B B. 0represents the hopper attached between the upper ends of the posts A A,and occupying the entire space between the same,

, thereby increasing the capacity of the same.

In the bottom of the hopper are a number of openings, to, arranged on astraight line, and under the hopper is a slide, b, to close saidopenings or either wholly or partially open the same. D and D representtwo inclined shoes, each provided with two sieves, E E, and a bottom, G.At the upper end of each shoe is a vertically-sliding door, H, and eachsieve has an inclined spout, I, at its lower end, the two spouts in eachshoe inclining toward opposite sides. In the bottom G is an aperture, d,as shown. The upper shoe D rests, at or near its upper end, upon asquare bar, J, journaled at its ends in suitable boxes attached to theposts A A, while the lower end is pivoted between and to the upper endsof two bars, K K, which are pivoted on the inner sides of the posts A A,at the opposite end of the machine. Between and to the lower ends of thebars K K is pivoted the upper end of the lower shoe D, and the lower endof the same is suspended, by means of pivoted bars L L, from the upperend of the upper shoe D. Upon one of the journals of the square bar J isplaced acog-wheel,M, provided witha crank or handle, N, by means ofwhich the bar J is revolved, giving a shaking motion to the upper shoeD. The cog-wheel M gears with a pinion, P, upon the outer end of ashaft, 0, which is, at about the center of the frame, provided with acrank, f. From this crank a spring-bar, R, connects with the lower endof the upper shoe D, and by this means the said upper shoe obtains itsreciprocating motion. The motion of the upper shoe contributes similarmotion. but in opposite direction, to the lower shoe D by means of thepivoted bars or levers K K.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent,'is-

The shoes D and D, connected together by the bars L and K, the bar Kbeing pivoted to the frame near its center, one shoe being pivoted toits upper and the other to its lower end, and the two operated as andfor the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this9th day of October, 1872.
